WHEEL AND RIM WITH WEIGHT REDUCTION SOCKETS

Abstract

A wheel and a rim with weight reduction sockets are provided. The rim includes an inner flange, a middle portion and an outer flange, the inner flange, middle portion and outer flange are all annular and are connected end to end to form a cylindrical rim, in which the middle portion of the rim includes weight reduction sockets; and the weight reduction sockets are of regular hexagons, and are arranged adjacently on the outer side of the middle portion of the rim in the shape of a honeycomb. The weight of the hub is reduced by designing the weight reduction sockets in a specific shape for the outer rim of the hub and selecting the size of the weight reduction sockets.

DETAILED DESCRIPTION

First Embodiment

[0023] The present embodiment provides a motor vehicle aluminum alloy hub with an outer rim having weight reduction sockets. The hub includes a wheel disc and a rim, and the wheel disc includes a flange plate, a flange plate periphery portion and spokes. Weight reducing sockets are provided on the outer side of the rim of the hub, the single weight reduction socket of the rim is hexagonal, the side length of the regular hexagon is 21 mm, the weight reduction sockets have a depth of 2.5 mm, internal fillets of R2, a rib width of 4 mm and a rib height of 1.5 mm; and four side form joint ridges of 10 mm are provided. By test, the weight of the hub is 11.29 kg in the absence of weight reduction sockets and is reduced by 0.95 kg in the presence of weight reduction sockets, and the weight reduction effect is about 8.4%.

Second Embodiment

[0024] Various properties of the motor vehicle hub of first embodiment were tested. The strengths and fatigues, including 13-degree impact strength, 90-degree impact strength, radial impact, radial fatigue, bending fatigue and the like, of the above wheel were tested in the test center of Dicastal. The tests show that the hub meets American Wheel Standards of SAE J175 and SAE J328-2005, namely meets the performance requirements for 13-degree impact strength, radial fatigue and bending fatigue, and also meets the requirements of GB/T 5334-2005 and GB/T 15704-1995 for wheel strengths and fatigues.
